PURPOSE: A concrete lining method on a large-scale underground cavity is provided to improve the construction performance and quality of concrete lining.;CONSTITUTION: A concrete lining method on a large-scale underground cavity is as follows. The allowable standard of vibration on a large-scale underground cavity is set. An optimum distance between concrete lining and excavation is calculated. Concrete lining is performed on the top head of the large-scale underground cavity, and a bench 1 is excavated as many as the calculated distance. A bench 2 and a bench 3 are excavated at the bottom end of the bench 1, and concrete for lining is placed on the benches.;COPYRIGHT KIPO 2012
